IMPROVEMENT- IN GAGE-COCKS.

Specification forming part of Letters Patent No. 53,555, dated April 3,1866.

To all 'whom it may concern:

Be it known that I, PHrNnHAs BALL, of the city and county of Vorcester,and State of Massachusetts, have invented certain new and usefulImprovements in Gage-Cocks; and l do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the accompanying drawings, forming a part of this specification.

In the drawings, Figure l is a longitudinal section with the plug P inproper position for furnishing water for use, as indicated by the arrowsa a a a. Fig. 2 is a similar section, with the plug turned in positionso as to shut the water off from use, and, opening the drainport t, thewater flows out of the service-pipe, thus leaving them emptied of theircontents, so as to prevent injury to them from freezing. Fig. 3 is asection, showing the gage closed and the port E in the lower end of theplug P turned against the passage m, whereby the water is forced in thedirection ot the arrows c c c andthe wire screen or filter is washedoff, and all sediment stopped in the chamber of the coupling B is blownor washed out of the chamber in B, and from the screen or lter throughthe opening D in the plug P into the open air. Fig. 4 is a top view, thepositions in which plug P has to be turned to effect the several objectsabove named being indicated by letters of reference.

My improved gage-cock is made at rst in the same manne-r as the commonplug-cocks, leaving the plug solid against the direct current ot' thewater, as represented by the arrows a a a a, Fig. 1. rlhe port a is thendrilled of such size as will be required to deliver therequired quantityof water under the given head. lhe parts of the apparatus are, first,the body K, constructed with the proper plug-socket P, which plug P,after being turned, is ground water-tight into its seat in the usualmanner. This body is cast with a water way or port, I I, andcleansing-port m, communicating with the chamber of the coupling B atthe supply end of the cock, and also with a drainway or port, t,communicating with the waterway on the service end of the cock. The plugP is cast solid above the water-ports m and t, and hollow in the centerbelow the port-line, having an orice opening into this hollow channel E,Fig. l, which is so constructed as to allow a free communication fromthe open air to both the supply and service ends of the cock.

Upon or over the water-way I, which is opposed t0 the supply, issoldered a screen or filter, S, the meshes or pores of which are smallerthan the gagingoriice n, the object of which lilter is to prevent any shor organic or inorganic substance passing this point ot' the water-waywhich could in any manner fill up the gagging-orifice n, and therebystop the iow of water, thus rendering the apparatus useless as a gagingapparatus. All substances arrested by this screen or filter are eitherretained by this screen or filter itself or are lodged and retained inthe chamber V, which is made of large dimensions for that purpose. Thelter S is put upon the end of the cock in an inclined position for twopurposes. One is to enlarge its surface, and the other is to have itsposition such as that, when it has become in any manner clogged byforeign substances in the water, by opening the port m, so that it shallcommunicate directly with the open air through the orifice E and thetube D. Then the pressure of the water will cleanse the lter S and thechamber V of all accumulated obstructions, and when so cleansed, thenthe apparatus will continue to act as when first put in operation.

The chambered coupling B is screwed upon the body of the apparatus K, asseen in Figs. l, 2, and 3, and the whole apparatus is then put in lineof any supply-pipe in any desired position by being coupled to thesupply-pipes by the screws, as represented.

The operation of the apparatus is as follows: After the cock has beenproperly connected in the line and ready for use the point of the arrowor the plug P, Fig. 4, is turned toward O, Fig. 4, and then the water isflowing in its proper supply-course, indicated by the arrows a a t a,Fig. l.

When the filter or screen has become fully or partially obstructed,then, by turning the point of the arrow, Fig. 4, toward C, the port m,Fig. 3, will be opened, and the chamber V and the filter S will becleansed by the force of the water; and when it is desired to empty ordrain a portion of the service-pipes beyond the cock to prevent freezingor for any other purpose, then the point of the arrow on the plug 2. Thecombination of the coupling B With P, Fig'. 4, should be turned towardW, and the body K, having a Water-Way, I, and port m,

port t is opened, as shown in Fig. 2. arranged and operatingsubstantially as set i Having described my improved gage-cook, setforth. what I claim therein as new and of my inven- 3.
